经过30年的改革开放,2007年我国国内生产总值达到24.66万亿元,经济总量跃居世界第四位,成为名副其实的经济大国。最近一段时间以来,由于全球金融风暴的冲击,我国经济发展面临重大挑战,产业结构不合理、质量损失率偏高的矛盾日益突出,成为制约我国经济稳定发展的桎梏。 After 30 years of reform and opening up, China's GDP reached 24.66 trillion yuan in 2007, ranking the fourth in the world in terms of economic output and has become a veritable economic power. Recently, due to the impact of the global financial turmoil, China's economy faces major challenges in its economic development. The contradictions of an irrational industrial structure and a high quality loss rate have become increasingly prominent, which have become the crux of restricting the steady development of China's economy.
